Lemi never really gets to have privacy at home. 
Sure he has his own decently sized room, but with his Mom and himself living in a small flat where closed doors are almost never a thing, and every single sound can be heard from anywhere in the flat happening anywhere in the flat, he really doesn't get to have much time for his own desires and interests to be satisfied. 
Over the span of a few years since he's started to explore what makes him feel good, he's found a few ways to do what he loves without being caught. 
Be it make up excuses to close his room's door or wait for his mom to be out of the apartment. 
But these were only temporary and very restricted times. 
That's why Lemi was so excited, when he got back to his school dorm after summer, to hear his previous roommate moved schools, and Lemi now owned a whole room with no roommates or neighboring rooms being occupied next to his. 
Lemi realized how good of a chance this was, and as soon as he could he grabbed his gear from home, stashed it in his bag, and smuggled it into his new personal room…

By the time Lemi reached his dorm, after traveling for a few hours by bus from his hometown to here, it was already getting dark, 9pm quickly rolling around on the clock. 
As the bird unpacked his stuff, clothing, hygienic products, and some snacks, he quickly took out the hose and hand pump and hid it under his pillow. 
His door was closed and all but he still didnt want to risk anyone barging in unannounced and catching him with such strange equipment. 
After putting his empty bag away, and hearing that curfew was due in a few minutes, Lemi changed into his most comfortable, loosest pajamas he owned, and got into bed. 
The staff went around checking each room for anyone not ready for bed yet, Lemi was in the clear, and after a few minutes of steps and some voices resonating through the outside halls, two clicks sounded, and the lights in the hallway all went dark. 
Everything went smoothly, and Lemi couldn't believe it himself. 
He took a deep breath and pulled out the pump and hose from under his pillow, after putting them together and making sure they stuck, Lemi rolled onto his side and with a quick yet rough motion, the other end of the hose was now stuck inside of him. 
Obviously not being able to control himself, his pajama pants started to tent and his breathing got heavy. 
He couldnt believe that he was finally free to inflate in peace, and for as long as he could handle too. 
He never got to really explore his size limits due to the stress under which he was at home anytime he tried to inflate, but now? He had all night to explore to his belly's content.
With some small adjustments and positioning, the birb got ready by laying on his back, keeping the pump under his leg so it wouldn't move, and placing his paw on the handle, it was time, and he couldn't wait any longer. 
With a slow yet needy push on the piston, air started to enter Lemi's body, at first filling up his lower guts, but after a few more pumps making way inside of his empty stomach. 
The birb made sure not to have any dinner and do all the preparations needed for the best experience possible beforehand, and with his stomach empty, only sporting some water from earlier for hydratation, bubbling could be heard and felt from within the young boy. 
Lemi shuttered and pushed in a few more pumps of air at a pretty steady and comfortable pace, making the bubbling louder and more prominent from within. 
The bird didn't expect this but wasnt complaining since as he noticed he was holding in said bubbles of air easily and started to feel a bit bloated. 
Nothing was visible just yet on the feathered tum but that soon changed. 
As he started to pump at the same steady pace as before he started to feel the good old push he was oh so in love with, it signified his stomach has filled up in its current shape, and soon the air would start to bload the stretchy organ bigger to contain itself within. 
The boy kept on pumping with one hand, the other placed on top of his stomach, feeling the growth and movement from inside.
In his mind, he knew how weird this was, and how unnatural it feels, but he still wanted more. 
He didn't know what it was but there was something about feeling full and tight and stretched that made him excited beyond belief. 
As he was laying there, pumping away at himself, his pajamas started to finally fit him for once, his belly didnt grow that much bigger just yet but his top was already starting hug around the growing width. 
Each time Lemi pumped and his guts bubbled, he would feel the need to blech as air moved further into his body. 
Lemi tried to relieve the preassure a few tines with some half assed burps but after seeing that not even being a litteral balloon helped him to burp properly, he decided to just give it up and hold said air inside, the results of this being his chest starting to rise along with his tummy. 
Lemi was now starting to reach a size he's never reached before, his stomach was swollen and tight, growling, upset at how stretched it was starting to get, the birb's other hand now doing its best to rub the orb of a stomach into comfort, yet Lemi still didnt feel any pain. 
It was getting hard for him to pump, both because of the stomach obstructing the pump slowly, and because of the ammount of gas inside of Lemi. 
Each pump was getting harder and harder to stuff inside with just one hand, and so Lemi decided to take a break for a bit and get accustomed to his new size. 
He placed both of his paws on his feathered stomach, breathing steadily. 
He didnt rub it or anything, he just closed his eyes slowly and focussed on the air inside, how it was moving, how with each breath out his tummy didnt shrink in any way and he could feel the preassure that was forcing this state. 
He just ended up laying there for a few minutes, breathing heavily and listening as his guts complained, it was all just making Lemi even more excited. 
He knew this was wrong, especially wrong for someone his age, but he didnt care as this felt right, this felt awesome. 
Lemi's previously tenting pajama pants have been pressed up against the tight underbelly for some time now, rubbing away and painting the pants with pre. 
With one last deep breath Lemi pulled the pump from under his leg and held it with both of his paws, one holding the base and the other the handle, he knew this was his first time properly inflating, but he wanted to reach his limit no matter what, no break it or extend beyond it, he just wanted to feel the tightest, fullest possible without hurting hinself. 
And so, with a significant increase in pace, the young birb boy started to force himself to grow even bigger, his stomach has already obstructed some of his view, making most of his legs dissappear, but he wanted more. 
He pumped and pumped, huffing and gently moaning, trying to make sure not to let out many loud noises, but with the growing preassure this was getting impossible. 
Lemi's member was now completely rubbing and trying to get off against the growing ball of a stomach, which was starting to show due to the powerfull throbs spurts of pre everywhere. 
Lemi could see none of it, but he could definitely feel it, only making him hornier for more air. 
He didnt know how big he's gotten, if he was anywhere near his limit or not as this was all new to him, but he felt like an overinflated beachball, and he almost even looked like one, only with the addition of red stretch marks forming around the vertical parameter of said beachball. 
It was starting to hurt, but to the lusty teen this just ended up feeling like added pleasure. 
The air whirled around his insides, stuffing even his throat which he had to clear by gulping down on the air trying to escape, his lower guts felt like they were gonna explode anytime soon if he didnt stop, but instead they just kept releasing slight bits of the air back the way it came. 
It seemed as if Lemi was content with popping right then and there, but then, a moan escaped the boy with heavy breaths following, his pants feeling a sudden intense wetness. 
He thrusted against the ticking time bomb, shooting strings of his juices all over the lower side of his stomach, going straight through his pants. 
Quickly his hips settled down and as he felt a few last drops of cum escape his member, he dropped the pump from his paws and just went limp. 
His stomach was loudly growling and almost moaning, Lemi felt sharp pains suddenly wash all over, forcing him to let air espace from both his ends with long and loud embarrassing sounds following. 
Lemi's breaths suddenly got short and quick, he was panting like a dog, his eyes were teary, and his body shaking, his stomach started to shrink slowly but the more it shrank the weirder Lemi felt, the loose skin on his body from the stretching being the source of this strange feeling…

Try as he might, Lemi couldn't get all the air out of his body for the longest time, his stomach was still whirring with air that was left inside, leaving Lemi feeling bloated, he supposed this was his punishment for getting so carried away, but with full honesty, he enjoyed being punished like this, his tummy hurt whenever he breathed out and he stayed a little swolen for the remainder of the night, but whenever he felt a little jolt of pain his drained member throbbed. 
He spent the rest of the night cleaning himself up with lots and lots of tissues, and when he was done, his whole body felt like it had been all used up. 
As he laid in bed, motionless, his mind was trashing about, feelings conflicted, lewd ideas appearing in huge ammounts, himself wondering if he hadn't came if he'd make himself burst. 
As all these ideas came to, it made the bird boy tired, and after he got fed up with so much info being thrown around in his head he decided to just drift off to sleep…

The next morning Lemi overslept big time. 
As he woke up he noticed he never disconnected himself from the pump and hose, hopefully none of the staff checked on him and saw it, that'd be really awkward to explain if he even could explain it. 
As Lemi sat up he felt a push in his guts, and as he looked down he was still sporting a little bloated tummy, the same as yesterday, and he felt very airy, he tried and managed to burp quite impressively, better than he ever could actually, but no matter how much he burped the bloat stayed, it wasnt really in the way or anything, it was kind of cute actually, just really sensitive. 
Lemi decided to just shrug it off and after checking the clock he knew there was no point in getting to class anymore either, so he just decided to stay in bed, watch some films and rub his new sensitive bloat that didnt seem to be going anywhere anytime soon, later making the excuse he felt sick being the reason he didnt go to class.
